Abstract

MCM-41-SO3H: An efficient and green reusable catalyst for the synthesis of 1-amidoalkyl 2-naphthols under solvent-free conditions and microwave irradiation

Author(s): Hassan Ghasemnejad-Bosra

An efficient and direct protocol for the preparation of 1-amidoalkyl 2- naphthols employing a multi-component, one-pot condensation reaction of â-naphthole, aromatic aldehydes and acetamide in the presence of MCM- 41-SO3Hinwater under solvent-free andmicrowave conditions is described. In this method, several types of aromatic aldehyde, containing electronwithdrawing groups as well as electron-donating groups, were rapidly converted to the corresponding amidoalkyl naphthols in good to excellent yields. The thermal solvent-free and microwave green procedures offer advantages such as shorter reaction times, simple work-up, excellent yield, recovery and reusability of catalyst.
